- A. Principal Muscles: Diaphragm , External Intercostal.
- B. Accessory Muscles: Sternocleidomastoid , Scalene (Anterior/ Middle/Posterior), Serratus Anterior, Pectoralis Major and Minor, Upper Trapezius, Latissimus Dorsi, Erector Spinae (thoracic), Quadratus Lumborum.
Muscles of Expiration
- A. External Intercostal
- B. Abdominals
INDICATIONS
IMT is effective and indicated in the patients having:
- COPD Asthma
- Interstitial Lung Disease (ILD) Bronchiectasis
- Diaphragm Dysfunction/Paralysis
- Thorax Deformations (Kyphoscoliosis)
- In Patients with Neuromuscular Disease
- In patients with Inspiratory Muscle Weakness and a Ventilatory Limitation to Exercise.
- Pre- and Post-Operative Thorax Interventions (Lung Transplantation, Coronary Bypass surgery)
- Neuromuscular Diseases (DMD, SMA, MS, MND)
- Competitive Athletes (Endurance Sports)
BENEFITS of Inspiratory Muscle Training (IMT)
Inspiratory Muscle Training (IMT) has shown to:
- Improve Strength, Endurance and Capacity of the respiratory muscles
- potentially positive effect on symptoms
- Increase Exercise Capacity
- Reduce Breathlessness
- Improve Quality of Life
- Decrease the use of health services
DEVICES
to increase the STRENGTH and ENDURANCE of INSPIRATORY as well as EXPIRATORY muscles
Inspiratory Muscles Trainer
Expiratory Muscles Trainer
Inspiratory and Expiratory Muscles Trainer
Respifit- S
An Individual Device used to:
- Assessing the strength and endurance of Inspiratory Muscle
- Strength and Endurance Training of Inspiratory muscles
Measure of Inspiratory Muscle strength and Endurance:
1. Maximum Inspiratory Pressure / Peak Inspiratory Pressure (PImax)
- An Important and Non-Invasive index of Diaphragm Strength
- Inspiratory muscle weakness defined as PImax < 60cm H2O or < 50 % predicted.
2. Minute Ventilation
- Training volume per minute
3. T(lim) Assessment
- Time to exhaustion of the respiratory pump against a variable inspiratory resistance.
RESEARCH BASED EVIDENCE
Numerous clinical studies have shown that IMT improves respiratory muscle function leading to an increase in exercise capacity, a decrease in perception of dyspnea, decrease use of health services and hospitalization and an overall improvement in quality of life.
